We predict experimentally accessible signatures for helical Majorana fermions on the edge of a topological superconductor by coupling it to two spin-1/2 quantum impurities. Taking into account RKKY interactions mediated by both bulk and edge, where the helical Majorana edge modes cause a long-range... continua

Leptogenesis is a class of scenarios in which the cosmic baryon asymmetry originates from an initial lepton asymmetry generated in the decays of heavy sterile neutrinos in the early Universe. I explain why leptogenesis is an appealing mechanism for baryogenesis, and I review its motivations and the... continua

Nucleon sigma terms are quantities that play an important role
in various areas: among others, they connect the pion-nucleon and the
kaon-nucleon amplitudes to the hadron spectrum and they are also
relevant for the direct detection of Dark Matter. Techniques to compute
them through lattice... continua

Graphene grown on metal surfaces is an exciting field of solid-state chemistry and physics from different points of view. Technologically, this is the main and the most perspective way for the large-scale preparation of high-quality graphene layers of different thicknesses with controllable... continua

Graphene layer on metal surfaces have been attracting the attention of scientists since several decades, starting from middle of the 60s, when catalytic properties of the close-packed surfaces of transition metals were in the focus of the surface science research [1,2]. The recent demonstration of... continua

2D molecular self-assembly on metal surfaces: understanding the effect of the formation of molecular dipoles

An overview is presented of the dynamical emergence of coherent structures and intermittency in a variety of plasma systems ranging from MHD to kinetic (Vlasov/PIC) plasma at a wide range of scales. Temporal intermittency at low frequencies, and spatial intermittency in the inertial rand and in the... continua
